I hope I can find enough time and energy to finish this one. I don’t know anything (not even the name of the tools) about woodworking, and I haven’t done any large scale modding/building (I am not counting assembly of my computer/changing heatsink fan/chipset cooler

There’s gonna be an intro level woodworking class starting 3 weeks from now. Hopefully I will have access to lab and tools, and they already mentioned that we should come to class with a small project in our mind. My project will be the computer case.
Being said that, you might ask why wood? I want a silent, custom computer case with my current parts and more importantly want to get familiar with the material. Here is the side view of the case:

Draft:
Case material: pine.
Dampening material: fiberglass covered with some fabric (on the left side of the case).
Dimensions: 8.5x16.5x18 (WxHxD).
Weight: unknown.
Intake fan: Two 120mm intake at the front bottom of the case (feet of the case is not shown above picture)
Intake fan: One 80mm intake at the top of the case for mosfet area
Exhaust fan: One 120mm exhaust at the back of the case
Fan controller will be installed to make sure whisper quiet case J (dreams)
PSU will be at the bottom of the case
5 bays for optical drives / 2 for hdd / 1 for floppy
Not sure about usb/1394/front audio
I think I might have to buy a $40-45 case just to get mobo tray, 3.5&5.25 bays, usb connections, power switch…
If you know a cheap case with removable mobo tray that would be awesome (I found this: http://www.dealsonic.com/skmssialatxm.html for $42 including shipping, but perhaps you know a cheaper one)
Also, what do you think about the design of the case (I’ll draw front, top, and back views later)?. Do you think can I turn the psu 180 degrees so that its fan will look inside the case?
I will update this thread as I start doing more. Your ideas, comments are more than welcome.
Cheers
